Airbag control unit with part number 22922718

What does the airbag control unit 22922718 do?

The airbag control unit 22922718 manages the restraint system (SRS) for Opel. It evaluates the measurement data of the crash sensors, decides in an accident within milliseconds on triggering airbags and seatbelt pretensioners, and indicates faults via the airbag warning light.

The system is checked constantly during operation. This monitoring runs in the background and is not visible in everyday use.

After an accident the unit stores crash data and locks itself. The following sections show what consequences this has.

Why does the control unit 22922718 fail?

The most common cause for the 22922718 is storage of crash data after an accident, even when no airbag was triggered. A standard diagnostic tool cannot erase this data. Ageing components, moisture and voltage spikes are also possible.

The stored crash data are thus the most common reason for failure, even though nothing may be visibly wrong. The diagnostic tool cannot erase them.

Ageing electronic components, cold solder joints and corrosion at plug connections are likewise among the possible causes. A weak battery or a jump-start produces voltage spikes that stress the electronics.

How can you tell that the 22922718 is defective?

A defect in the 22922718 shows up through the airbag warning light, which stays on permanently or lights up intermittently, through a fault message in the instrument cluster, through a missing connection to the diagnostic tool and through a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

In detail, these are the signs:

• The airbag warning light in the instrument cluster stays on or lights up repeatedly.
• The instrument cluster reports a fault.
• The diagnostic tool finds no control unit.
• The fault memory cannot be cleared.

If you notice one of these signs, have the fault memory read out before taking further steps.
